The 6AW8A is a high μ triode and a sharp cut-off pentode. The design use was as a sync separator and video amplifier. The electrically identical 8AW8A has an 8.4 Volt 0.45 Amp heater.
The RCA data_sheet describes the 6AW8A thus: 'miniature type used in television receiver applications. The pentode unit is used as an IF amplifier, video amplifier, AGC amplifier or reactance valve. The triode unit is used in low-frequency oscillator, sync-separator, sync-clipper, and phase-splitter circuits'.
This valve has a special silver oxide coating that looks to be absent on the eight Volt version. Could the coating reduce emission from the glass?

The thin glass tube envelope is 20 mm in diameter, and excluding the base pins is 59 mm tall.
Reference: Data-sheet. Type 6AW8A was first introduced in 1956. See also1956 adverts.
